dubbi rotazioni

Salve ho un dubbio nel calcolo del baricentro per rotazioni non complete in un dominio del tipo D{x^2+y≤1, x≥0,y≥0} con a=5π/6 Asse y, versoz positive.... Volume e cord y li ho calcolati ma quando devo andare a trovare cord. x e z del baricentro non riesco a trovare gli estremi di integrazione per la terza coordinata (in questo caso z)... NB ho usato le polari x=rho cos(theta), y=y, z=rho sin(theta) ....grazie

ho poi invece un altro dubbio... in classe abbiamo dim che se una curva in un dato intervallo è monotona in un pezzo di intervallo e poi anche nellaltro pezzo allora con gli opportuni accorgimenti da fare riusciamo a dire che e semplice... ma se invece in un pezzo è crescente e nell'altro è decrescente si può concludere che non è semplice;
- se poi ho una curva del tipo (t, sint) e per dimostrarne la semplicità su[-π,π] volessi applicare la def trovo subito t=s e sint=sin s... cosa posso dire a riguardo?

scusi volevo scrivere "si può concludere che è semplice";

Sono nelle sezioni sbagliate, quindi a breve saranno spostati, poi ti risponderò.
